Customer Ratings & Reviews

What I really like: • The speed bump is legit noticeable. On my iPhone, it pulls close to full 25W wirelessly when aligned right—I’ve seen it push from low battery to ~50% in about 30 minutes, sometimes faster if the phone’s not too warm. That’s roughly 30-50% quicker than my old 15W banks. No more babying it for a quick top-up before heading out. • Magnets are rock-solid. Snaps on with a satisfying click and stays put even if I’m walking fast or tossing it in a bag. No sliding off like some cheaper magnetic ones. • Built-in USB-C cable is a game-changer—no extra cable to lose. Recharge the bank at 30W or use it to juice another device wired. Super convenient for travel or desk chaos. • Blue color looks clean and modern; doesn’t show fingerprints as badly as matte black ones. Build feels solid—premium plastic, no creaks, and the cable feels durable so far. • Heat management is better than I feared for 25W wireless. It gets noticeably warm during heavy charging (especially the first 10-15 mins at peak), but it throttles smartly and never gets uncomfortably hot to hold. Way more tolerable than some early high-wattage attempts I’ve tried. The downsides (keeping it real): • It’s chunky for a 10K pack. Thicker and heavier than your average slim 10,000mAh (like Anker’s MagGo or whatever). Fine in a jacket or backpack pocket, but jeans pocket? Nah, it’s a bulge. If you want ultra-portable, look elsewhere. • Wireless charging drops off a bit with thicker cases (over ~2-3mm) or if it’s slightly misaligned—standard Qi2/MagSafe thing, but at 25W you feel the difference more than at 15W. • Price is on the higher side for a 10K magnetic bank, but you’re paying for that Qi2.2 certification, speed, and the built-in cable. Not a budget pick. • Efficiency isn’t the absolute best in class (some tests show real-world delivered capacity around 60-65% after losses), but it’s competitive with other 25W models. Bottom line: If you’re all-in on fast wireless charging and hate juggling cables, this is easily one of the best 25W Qi2 magnetic power banks out right now. It’s fast, reliable, and feels future-proof for newer iPhones. loses a bit for size/weight, but wins big on performance and convenience. The blue one looks sharp too. Highly recommend if speed > slimness for you

Charges fast and the magnet is actually pretty good

I bought this item for a trip and it has been one of the most useful things I've ever owned. It worked perfectly throughout the trip and never let me down. Great purchase.

It’s a reliable fast charger that can attach via MagSafe, which is great. Unfortunately it’s really bulky and the cable that’s on it is way too short to actually be utilized.

It gives you at least 2.5 charges you’re phone, so up to today is been a good product.

Excellen service. The staff was very knowledgeable, very attentive, extremely king and helpful

Love it! My phone doesn’t die on me anymore! I charge it and keep it in my purse.

It has only one usb-c port which is cumbersome to charge

Awesome device; i strongly recommended to you; excellent…!!!!!!

I love it! I bought it to take to Disneyland. Great product!!

My husband loves it! He uses it all the time Good value.

Very bulky and way overpriced didn’t even charge my phone had to return it sadly.

This portable charger is good but expensive compared to other brands.

In terms of build quality, it feels pretty solid. It feels fairly durable but as I have learned with all things these days, only time can truly tell if it passes the durability test. The design feels very sleek and modern. I think the screen adds a nice touch and it showing the exact battery percentage is a nice touch. The included built-in cable also functions as a strap. I don't know if there are other devices currently and previously on the market that implemented that idea. I am a little bit skeptical about it. The cable definitely feels durable although I feel like all of my cables eventually fail. This one is surely to suffer even more abuse due to the function as a strap. I wish there was a way to hide the cable completely or make it retract into the charger so that it can be protected at times. Given the angle of the cable as well, you also have to rotate the cable 90 degrees when you plug it into the phone so that I feel like will also strain it. That being said, I do like having a built-in cable as it is one less thing I have to carry around. The magnet for Magsafe works like a charm and I was not worried about my phone shaking around on it. The actual wireless charging is decent. If your phone is compatible, 25W charging is pretty fast and should be able to charge most of your battery in an hour. If you are a bit inpatient, the wired charging is 30W. 10000mAh is a decent amount and I was able to get about 2 full charges on my phone. I personally have been really happy with this Ugreen portable charger. The strap is both a plus and minus for me so everyone's mileage may vary.

This power bank is fantastic! It supports both Qi2 25W wireless charging using the MagSafe connector or wired charging using a built in USB-C cable that doubles as a lanyard. Yes you can use both at the same time, but keep in mind when you add more than one device you are limited to 25W max output so things will slow down slightly. The unit is easy to hold, solid without being bulky, and while it’s not something you are going to be carrying around in your pockets, it is compact enough that it won’t cause too much of a burden to carry it with you in your travel bag. The reflective white/grey color of the unit helps you see it when it inevitably is sucked by gravity into the lowest crevices of your bag. I love that it has an LCD display showing current charge levels. This is also the only thing wrong with this device because when the device is plugged into the wall to charge the battery, the LED remains fully illuminated and blinks the second digit continuously to inform you that the unit is charging. I could not find a way to turn this off. Having a bright flashing LED in your bedroom at night while trying to sleep is not ideal. This thing has been fantastic sharing among a family of power hungry mobile users and at one point I even used it to slow charge my MacBook Pro. I’m not sure what else to say about this unit other than to go buy one immediately.

As the title indicates, this is a really fast charger for its type. First, it charges pretty fast with a high wattage charger. You can also use it to charge your iPhone with MagSafe or any USB-C device with the built-in USB-C cable. The MagSafe connection to my iPhone is really strong, even in a MagSafe case, and charges it as fast as other high speed MagSafe Chargers. It’s also super slim and low profile making it easy go carry with you on the go. The built-in USB-C cable is also braided and high quality, giving me confidence it will last for many users without breaking. The built-in USB-C cable also has a dual functionality, serving as the charging method for the battery itself. This gets rid of the need to carry anything but your phone and the battery with you. The battery itself is also roughly 2x the size of the iPhone 17 Pro Max battery so it provides a lot of one the go power. Overall, it also feels really well made and sturdy, giving me even more confident about it lasting a long time.

Item developed an error code during the initial charging process. I was unable to use it and returned it to Best Buy 24hrs after I purchased it.

While a battery is a battery and nobody is reinventing the wheel on a portable charger, it’s good to differentiate the good from the bad. Out of the box, everything besides the unit is recyclable. I’m not familiar with the Ugreen brand but without looking them up, judging by the name, they may have some eco-friendly ethos, which is always a plus for me. The box came with instructions, th charger and a USB-C to USB-C cord. The battery is, as you guessed, very easy to setup and use. I’m sure results vary but my charger arrived at 43% battery, which is nice if you picked this off the shelf, to know it’s likely got some juice. The battery is thicker than my iPhone 16 by a margin and certainly heavier, keep that in mind as you likely won’t be sliding this discretely in your pocket, especially while in use. I started by charging up the battery itself, which certainly is easy because… there’s already a USB-C cord “permanently” attached to the charger. I just plugged that into my USB-C adapter and off to the races. Conversely, you’re also able to just use the USB-C external cord to charge this as well, but I guess the only reason you’d do so if you were both charging the MagFlow while charging your phone/device. The options on how to charge your device are the MagSafe/magnetic wireless device, the hard wired usb-c, or an external usb-c. You can also charge multiple devices at the same time, which is great. The charger has it’s own battery life easily displayed in large LED on the side and what I will note is that the device seems to charge faster while using a USB cord over the MagSafe, but it also depletes the external battery quicker than anticipated. For example, I charged my phone, while using it for basic texting functionality, for 10% of the MagSafe battery life, and it only raised my phone battery by 6%, though it did that over 15min. Obviously there’s too many variables here, but you’ll want to expect this to act as a quick charge, more than a battery that’ll be charging multiple devices at a time without replenishing. The external battery life though is the biggest area for improvement as I don’t think it should only last about 2 hours. The magnet power is noteworthy for its strength. You’d have to really whack your phone to dislodge it from the magnet. The hardwired usb-c cord is not only great since it’s a clutter saver, but it also doubles as a carrying strap. How useful will that be after usage over year? Will the wire fray? Who knows. The downside here though is you can never fully “put the cord away”, you can extend/shorten it but it’ll always be in the way. For what it’s worth, they claim this is airplane safe, and I will note that I never experienced any overheating while in use. All said, the powerful, multi-use battery with built in cord and strong magnet makes this a great buy and while I won’t dock them on the always present cord, I do have to note the external battery life leaves a bit to be desired and settle this at 4 stars.

Heats up a lot and is very slow at charging takes a long time to get my phone fully charged

I have been using the Ugreen MagFlow power bank for a couple of weeks now and have been quite impressed so far. First things first. The unit itself is relatively large which is to be expected based on the capacity. It adds substantial thickness when connected which makes the phone a little awkward to hold, but if that’s an issue, you can always use the built-in USB-C cord and go that route. (The cord doubles as a carrying handle, but I wonder about the damage that those stresses might have on the cable itself so I try not to use it for that.) There is also a spare USB-C port for powering devices that aren’t MagSafe compatible or don’t have a native USB-C port. Using the built-in cord or extra port also allows for slightly higher charging (up to 30W from 25W on the wireless side). On my iPhone 17 Pro, the battery pack protrudes out below the bottom of the phone a bit which is a minor annoyance but not a deal breaker. (For comparison, on a friend’s Pro Max, it fits nicely in the normal footprint of the phone.) There is a noticeable charging speed difference since the Ugreen uses the new Qi2 standard which allows for 25W power delivery instead of 15W under the old standard. In my uses, it takes about 30 minutes to go from 0-50% compared to about 45 with a 15W Qi power bank, and I can get about 1-1/2 phone charges before needing to plug it in. Of course, that only helps if you have an iPhone 16 or newer as older phones don’t support the higher wattage and charging speeds. When charging, the pack stays remarkably cool so there’s a lot less worry about thermal issues than with other battery packs I own and use. The pack itself takes about 2 hours to recharge so that’s something to keep in mind. There is a small LCD screen that displays the current state of charge of the pack so it’s easy to see just how much juice you’ve got with a quick glance. Also, if needed, you can, at least in theory, charge 3 devices at once (wireless, built-in cable, and spare USB-C port). Doing that drops the overall speed to about 12.5W so everything will take longer to top up. When a phone is using the wired connection, wireless charging is automatically disabled, but a press of the power button restores the functionality. Overall, I have been pleased with the Ugreen MagFlow and have very few reasons to complain. It’s easy enough to pack and the built-in USB-C cable means just a little less clutter in a bag and eliminates the need to carry a separate cable to charge the pack itself or any devices that can’t charge wirelessly.
